ELECTRICAL SYSTEM, EXTERIOR LIGHTING, POWER TRAIN
The blower fan for heat In my vehicle was replaced in October 2022, recently the Defroster will not engage and it is vital to winter driving. The mechanism that switches between which vent to blow out air was replaced and the Defroster will still not engage, rather it comes out of the heat and face vents. Shortly after the Defroster stopped engaging, the rpms will start fluctuating from 2 suddenly up to 6-8 without warning or acceleration then go back down and back up as if it's chugging along. Even when applying the brakes, this will continue to happen and there's concern for Rear-ending or crashing when this happens. When driving home 2 nights ago the county police pulled my vehicle over due to burnt out headlight, which was replaced less than 6 months ago. Took the car in to get bulb replaced today and multiple bulbs later, the light is not fixed and it was said to be electrical and need to go to another shop. Beginning to wonder if this is all a bigger problem about to happen with engine/ powertrain.. with commute to work in the dark and electrical problem in the headlight randomly and the acceleration issues there is definitely a concern for safety.

ENGINE
Vehicle stalled, steering column was shaking. Fortunately, this took place when leaving work parking lot. Had it happened on the road, driver and passenger safety would've been at greater risk. In addition, this particular issue could've resulted in a fire in the engine compartment. Took to mechanics and was informed that cylinder #3 was no longer contributing to engine function. Technician discovered cylinder was leaking from exhaust valves. Vehicle has not been inspected by the other individuals. Prior to this incident, vehicle was consuming oil at an enhanced pace although the oil light indicator would never turn on. Engine light didn't appear until cylinder #3 failed. It's important to note there is a previous (successful) class action lawsuit for the 2010-2013 models for the same exact reasons noted above. Missouri is in the process of filing a lawsuit for the 2014-2017 models.

ENGINE
Engine started sputtering, then vehicle was shifting hard and occasionally jerking forward while braking/at a complete stop. Check engine light came on. Found there was no oil left. Was less than 3000 miles since prior oil change. Dealer service sticker stated oil change was not due until 5000 miles (synthetic). Oil light never came on. After refilling oil, check engine light turned off and vehicle started operating normally. Discovered many others with problems with this vehicle consuming oil. Luckily, we caught it before engine failure, but obviously worried that this could happen at any time.

FUEL/PROPULSION SYSTEM
My Terrain just started stalling. And it happens a few times a day. This is not safe. I had my daughters with me in their car seats, as I pulled out from a stop sign it just died. I couldnt steer or anything. People coming down the road and I am stuck In the middle of a street until I could put it in park and restart. And then it happens again when in reverse. I thought I accidentally had it in neutral. I restarted it and thought it was fine. It gave a little chugging when I hit the gas pedal but all was fine until I stopped to pull into a parking spot and tried to reverse again to straighten my car. I turned it back on, then it was good enough to get out. when I went back to my car it stalled like 4 times when trying to simply leave the parking lot.

ENGINE
The engine burned a usually large amount of oil without warning the driver, resulting in engine failure. With minimal local driving and no warning, the engine was completely out of oil, resulting in an engine banging/rattling that began, resulting in total car failure. Like others with the same issue, a certified dealer diagnosed that a new engine was needed at a cost of $9500. An independent repair shop also confirmed a new engine would be needed.

My vehicle had 2 recalls and I took it to the local Chevy dealer where I had purchased the car in 2018. The windshield wiper problem was repaired but I was told they did not have the correct parts to repair the headlights. After 3 days I was told the car was ready and I was assured by the service manager that the car was done. However, the headlights were not repaired..

The timing belt on the GMC Terrains from 2013 to 2015, mostly 2015 are breaking at a unusual amount. If you google it , there is story after story about this problem and GMC has not done anything. This appears to be a problem with the Terrain and I want them to issue a recall before mine breaks. It is expensive to fix and it can also be a huge problem if it breaks when you are driving. Something has to be done as this is not a coincidence that this is occurring to a large amount of Terrains.

My GMC terrian has 98567 miles and had check engine light problem. Dealer said that I needed new timing chain. Cost $2282.05. Have not found a recall on the timing chain problem, but have seen many complains about the same issue. With some being replaced multiple times. Why has GMC not done anything to cure this problem. Van does not burn oil. Have it serviced at the GMC dealer since I purchased it with only 16000 miles.

Engine lost power suddenly while driving. No warning. Fuel pressure slowed to where vehicle no longer moved forward. Again. No warning. Timing chain slipped TWICE and destroyed engine without warning. “Engine power lost” appeared on dash from driving without warning or incident. Excessive oil consumption without warning. Smoking engine even though had regular oil changes. Engine had been inspected by dealership and allegedly had no issues. Car never smoked but did after second time of timing chain slipping/breaking. This issue has happened repeatedly to many drivers who own these vehicles. Had a difficult time stopping after engine and total power failure without warning.

ELECTRICAL SYSTEM
Not really sure if it is electrical but the Stabilitrak light came on and the car jerked and I could not go over 50 mph and that would be fine however when you are on a freeway and the speed limit is much greater you could cause and accident. I took the vehicle to a garage and they put it on there computer and reset it and it seemed to work OK until I again went on the freeway and the same thing happened. Again I took it back to the same garage and they recommended I take it to a GMC Dealer which I did and they could not find the problem either after spending around $600.00. I did take it to the GMC Dealer which the vehicle make is a GMC.The problem, to the best of my knowledge, started about April 2023.
